These devices automatically switch off the current in the controlled circuit as the pre-set temperature limit is reached, thus preventing overheating. Once the defection of the temperature regulation was repaired, in voltage-free state, the limiter / protective guard can be re-started manually.
Working temperature range: 0 – 355 °C
Areas of application:
– water heaters, hot water storage tanks
Trouble-free operation is conditioned by proper heat transfer between the protective limiter’s sensor and the controlled medium.
In case of capillary-damage or lquid-leakage, the device will cut the circuit one last time as positive safety-feature.
